Sensor, Humidity: Description
A humidity sensor (1) is used on Automatic Temperature Control (ATC) models to detect humidity levels inside the vehicle to optimize the dehumidifying effect of the A/C system. The humidity sensor is attached to a plastic bracket (3) by a metal retaining clip (2). The sensor bracket is attached to the inside of the windshield by an adhesive. A cover is attached to the sensor bracket by four plastic tabs (4). The humidity sensor is connected to the Body Control Module (BCM) by a dedicated three wire lead and connector that protrudes out from under the front of the headliner.
Use care when servicing the humidity sensor. The humidity sensor bracket cannot be serviced separately from the windshield. If the sensor bracket becomes damaged, the windshield will need to be replaced.
The humidity sensor can be serviced without the use of any special tools.
